DEVICE F'GR HANDLING HEAVY MASSES OF METAL.

SPECIFICATION forming part of Letters Patent No. 381,474, dated April 1'7, 1888.

Application filed January 25, 1883. Serial No. 261,854.

To all whom it may concern;

Be it known that 1, LUMAN F. JonNsoN, a citizen of the United States, residing at Cleveland, in the county OfOuyahoga, State of Ohio, have invented certain new and useful Improve ments in Devices for Handling Heavy Gastings, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of this invention is to provide a strong and convenient device to be attached to cranes and derricks for presenting in different positions for the operation of a steamhammer heavy forgings and ingots-such as, for instance, armor-plates, ordnance, c. and the invention consists in certain features of construction hereinafter described.

Referring to the drawings, Figure 1 is aside elevation showing the jib of a crane provided with a device constructed in accordance with my invention. Fig. 2 is a detail in plan of a gear-supporting ring. Fig. 3 is a detail in side elevation of a pulley-supporting sheaf or yoke, and Fig. 4 is a transverse section on the line at w of Fig. 1.

Similar figures of reference indicate similar parts in all the figures of the drawings.

1 represents the jib of a crane,which is supported in position by means of a diagonal stay, 2. The jib 1 is in this instance provided with the usual oppositely-located tracks, 3, upon which is mounted for travel an ordinary trolley, 4, carrying a central pulley, 5, these parts being shown in dotted lines, Fig. 1.'

6 and 7 represent the chains for moving the trolley upon the track 3, and 8 represents the draft-chain for supporting the sheave 9, having the pulley 10, the opposite end of the chain 8 being secured at one end to the trolley 4. It will be understood that these chains 6, 7, and 8 are connected with suitable operating-drums at the foot of the mast. (Not shown.)

11 represents acrosshead mounted between the sheaves 9 at their lower ends by means of trunnions 12. The cross-head 11 is vertically bored, and receives the upper spindle, 13, of a yoke, 14, said spindle being provided with a nut or other securing device, 15. Intermediate the spindle 13 and its depending hanger or yoke 14 is formeda bearing, 16, upon which is mounted for rotation collars 17 and 19, hav- (No model.)

ing oppositely-arranged inner-laced gears 18* and 18, respectively. A screw-threaded ring, 19*, is mounted above the collar 17 .upon screw-threads 20, formed upon the bearing 16 at its upper end, which ring serves to prevent the collar from rising from its seat in the hearing 16.

The yoke 14 is formed with oppositely-arranged bearings 21, in which is mounted a shaft, 22, carrying a loose pulley, 23, having a beveled facial gear, 24, bolted to one side thereof. a suitable chain, 25, which depends a suitable distance below the pulley and supports, in this instance, one end of a shaft, 26. One of the arms of the yoke 14 is provided with vertically-opposite bearings 27, in which is loosely mounted a shaft, 28, carrying at its lower end a bevel-gear, 29*,meshing with the facial gear 24 of the pulley 23, and at the opposite end of the vertical shaft 28 is'an ordinary gear, 29, which meshes with a larger gear, 30, formed upon the lower end of the collar 17 and below the bevel-gear 18 thereof.

In this instance there extends transversely through the diagonal stay 2 a transverse shaft, 31, which is connected with any suitable motor or engine (not shown,) which is provided with a bevel-gear, 32, which is fast thereon.

Mounted in bearings 33, projecting from the.

stay 2, is a shaft, 34, carrying at its lower end a bevel-gear, 35, which meshes with the gear 32. At the opposite or upper end of the shaft 34 is a second gear, 36, which meshes with a similar gear, 37, mounted upon a shaft, 38, transversely perforated, as at 39, and projecting from a plate, 40, which is pivoted to the face of the stay 2. The plate 40 is formed with oppositely-located bearings 41, in which is pivoted a shaft supporting hanger, 42, through which passes a shaft, 43, upon which is splined a bevel-gear, 44, which meshes with the gear 37, mounted upon the shaft 38, the shaft 43 passing through the opening 39 formed in the shaft 38.

Connected to the shaft 43 by a gimbal-joint, 45, is a short shaft, 46, having at its opposite end a bevel-gear, 47, which is mounted in a bearing, 48, of a supporting-ring, 49,for mesh with the two inwardly-disposed bevel-gears 18. The ring 49 has opposite bearings, 48,

Over this pulley isloosely suspended one of which, as before described, supports the shaft 46, the opposite bearing, 48, supporting a short shaft, 50, having a gear, 51, similar aperforated web, 49*, formed therein, through which the collars pass.

The operation of my invention is as follows: Motion imparted to the gear 32 through the medium of the shaft 31, which is connected with any suitable motor, is transmitted to the gear 35, its shaft 34, and to the gear 36, and from thence to the double gear 37 and the gear 44, which latter gear, being splined upon the shaft 43, transmits motion thereto and to the gear 47, which rotates the gear 18* in one direction and the gear 18 in the opposite direction. Thegearl8,beingformedupon thesame collar as the gear 30, said latter gear thereby receives motion and imparts the same to the pinion 29, its shaft 28, and its lower gear, 29*, and the latter gear imparts motion to theloose pulley through the medium of the facial gear 24, secured thereto, and thus the chain 25 is rotated and the presentation of the forgings supported therein in different positionsunder a steam-hammer is accomplished.

The gear 18 is simply an idle-gear, and, in connection with the bevel-gear 51, prevents any buckling or tendency of the shaft 43 to follow the, gear 18 when any unusual strain is exerted.

I do not limit my invention to any particular train of gearing for operating the same, but hold that I may vary the same in any manner desired.

By means of the chain 8 the device as a whole and its supported work may be adjusted laterally, in which case the shaft 43, its gear 44, and support 41 turn upon the pivot by which it is secured tothe stay 2.

In all horizontal adjustment by means of the trolley 4 and its chains 7 and 6, the shaft 43, being splined to the gear 44, slides hori zontally therein.
